COMBINED BlTT AND DECK=PEPE FOR VESSELS.

SPECIFICATION forming part of Letters Patent No. 387,894, datedAugustlt, 1888.

Application filed May 14, 1888.

To aZZ whom it may concern:

Be it known that I, FRANK S. llIANTON, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in Deck-Pipes;and I do declare the following to be afull, clear, and exenable othersskilled in the art to which it appertains to make and use the same,refer ence being hadto the accompanying drawings, and to theletters andfigures of reference marked thereon, whichv form a part of thisspecification.

My invention relates to ships windlasses; and its object is to improvethe deck-pipe or bushing through which the cable is passed into thechain-locker below.

As ordinarily constructed, the deck-pipe consists of a short cast-irontube having a flange around one end. It is fitted intoahole cut in thedeck and is calked to make a tight joint where it comes in contact withthe deckplanks. The surface of the casting is often rough and uneven,and consequently does not fit tightly into the hole, rendering itdifficult to calk it satisfactorily.

My improved (leek-pipe is cast in one and the same piece with theWindlass-bitt. The bottom of the combined bitt and deckpipe is planedofit" true and smooth,aud the surface of the deck is similarly prepared,so that the two surfaces will fit closely together. A coat ofcement--such as white lead or tar-on the bot tom of the bitt around the(leek-pipe makes a tight joint when the bitt is bolted down to the deck.

In the drawings, Figure 1 represents in perspective a starboardside bittprovided with my improved deck-pipe, and Fig. 2 is a side elevation ofthe same with the deck and (leekpipein section.

The Windlass-bitt A is a cast-iron one,similar to that shown anddescribed in United States Patent No. 197,040, granted to me November13, 1877. It is provided with a bracket, B, for the attachment of theclearing-guard, and is surrounded by a flange, a, by means of which itis bolted to the deck. Theshaft of thewindlass is received in thebearings D. Adjacent to the windlass-bitt,on the same side of it as thebracket B and lying with its axis in the vertical plane of the axis ofthe Windlass-shaft, is the deck-pipe E, which consists of a short tuberising from the flange a of the side bitt, said flange beingconsiderably widened for a portion of its length to surround thedeck-pipe on all sides, as shown. A web, E, unites the side bitt and thedeck-pipe and stiffens the latter very considerably. The pipeispreferably elliptical in plau,and is provided on its after half with aninternal bolster, e, to receive the friction of the cable and prevent itfrom catching on the edge of the deck-pipe as it enters thechain-locker.

A hole, F, is cut in the deck of the vessel to register with thedeck-pipe. Before the bitt is placed in position, the under surface ofthe flange c is planed smooth, and a coat of white lead is applied,which makes a watertight joint all around the deck-pipe when the bitt isbolted down.

Having thus described my invention, what l claim, and desire to secureby Letters Patent, 1s-

1. A cast'iron Windlass-bitt provided with a deck-pipe integraltherewith, substantially as described.

2. A cast-iron windlassbitt having alaterally-projecting flange and adeck-pipe rising from said flange and integral therewith, substantial] yas described.

3. The cast-iron windlassbitt A, provided with the flange a, thedeck-pipe E, rising from said flange, and the web E, uniting thedeckpipe and the bitt-,substantially as described.

4. The combination, with the deck of a vessel, having the hole F, of acast-iron windlassbitt provided with a deck-pipe integral therewith andregistering with the hole, the under surface of the bitt and deck-pipebeing planed smooth and coated with cement, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK STE AD MANTON.
